There is at least two types. One a lead alloy and the other zinc.

These are the lead alloy , a place my son worked at tossed boxes of new
weights when they converted . Most of the boxes made their way into the shop
manager's car ... my son managed to get one for me and no one ever asked
why the manager ordered a bunch of them shortly before the changeover ... .
I also got a bunch of used ones from somewhere , the ones that didn't melt
were all steel .
The lead alloy weights are alloyed with antimony to make them harder.
Will lead particles in the finished product be a problem? Because
there will surely be lead dust in the dust you are making.
